Rewriting method from a plugin - "Self" context

Overgrow · March 23, 2020, 12:20pm

Hello,

I’m trying to modify upload instructions from a plugin.

Can I use add_to_class to rewrite a class method that is in “self” context?

e.g. to take original method in OptimizedImage class

def self.resize_instructions(from, to, dimensions, opts = {})

and overwrite it in plugin with something like
add_to_class(:OptimizedImage, :self.resize_instructions) do |from, to, dimensions, opts|

This is obviously not that straightforward …
Thanks!

You would use add_class_method

github.com

discourse/discourse/blob/main/lib/plugin/instance.rb#L200-L212


      
            Discourse.deprecate(
              "replace flags should not be used as flags were moved to the database. Instead, a flag record should be added to the database. Alternatively, soon, the admin will be able to do this in the admin panel.",
            )
            next_flag_id = ReviewableScore.types.values.max + 1
          
            yield(settings, next_flag_id) if block_given?
          
            reloadable_patch do |plugin|
              ::PostActionType.replace_flag_settings(settings)
              ::ReviewableScore.reload_types
              ::ReviewableScore.add_new_types(score_type_names)
            end
          end
